It's been eleven years since Toulouse last won in Clermont, losing on their last eight visits to Europe's best guarded fortress. But those numbers don't tell the whole story...

The defending champions have left with a losing bonus point after five of those eight games in Volcano Country. Indeed, clashes between les Jaunards and les Rouge et Noir have become highlights of the French fixture list over the past decade and seldom disappoint.

Just how seriously Toulouse will take their chances of victory this time remains to be seen however. With Clermont - who are unbeaten at home in 58 games - hosting Bordeaux next week, it seems almost impossible for Toulouse to break into the leading duo so Guy NovÃ¨s could well focus on next week's home game against Grenoble, when les Toulousains should secure a home play-off spot.

Clermont have had a run of massive clashes. Their Heineken Cup quarter-final win over Montpellier was followed by a top-of-the-table draw with Toulon. This weekend's clash with another of Europe's top clubs will be perfect preparation for next week's showdown with Munster in the HEC semi-finals.

Victory this week for Clermont will see them equal Stade FranÃ§ais' record for an unbeaten streak on home soil.

Former All Blacks fly-half Mike Delany made an impressive debut for Clermont last week having trained for just three days with his new team-mates. He should feature again as Brock James is still sidelined and David Skrela is doubtful.

Good news, however, is that Luke McAlister and Louis Picamoles should be available.

SU Agen v USA Perpignan Stade Armandie, Agen

A big win is non-negotiable if Perpignan hope to remain the race for the play-offs. The Catalans are six points short of Montpellier, who travel to Bayonne, meaning that USAP need two favourable results to stay in contention.

Condemned to relegation, the player drain at Agen has already started with at least seven first-choice players on the departure list. Jean Monribot, Sylvain Dupuy, Romain Edmond-Samuel, Opeti Fonua, Ueleni Fono, Lisiate Fa'aoso are set to play their last games in front of the Stade Armandie faithful. SaÃ¯moni Vaka is also on his way out but has a broken arm, so won't feature.

Montpellier can secure a place in the knock-out stages with victory this weekend and will fancy their chances at a venue where they've won on their last two visits (17-26 last year and 18-29 in 2011).

Failure to get the job done will set up an almighty showdown with Perpignan for the last remaining play-off spot on the final day.

Montpellier have won their last three games - away to Grenoble and Mont-de-Marsan before edging Toulouse at home - so they seem to have found some form at just the right moment.

Bayonne's only remain goal will be to try finish above their Basque rivals Biarritz, whom they trail by three points. The hosts will be without Benjamin Boyet and Gaby Lovobalavu but welcome back prop Neemia Tialata and wing Bastien Fuster.

Montpellier will travel with an unchanged squad. FranÃ§ois Trinh-Duc is still the most notable injury absentee.
